Well this came out ok considering the moon was out.
Mounted the 5d MK3 with the Sigma 600mm mirror lens on Neq6pro.
This image is built from
50 Lights @ 45 sec
50 Darks @ 45 sec
50 Flats @ 1/80 sec
50+ Bias @ 1/8000 Sec
this was a test really to work out a work flow to gather all required to get the best from the setup using DSLR
Me thinks to get it better do more of all subs.
this was also a test for the Pixinsight processing package
happy days
